WATER-GOOLED BEVERSING-VALVE.

Specification of Letters'Patent.

Patented April 28, 1908.

Application filed. July 3, 1905. Serial No. 268,070.

To all whom it may concern:

Be it known that 1, JOHN BARNES, of Portvue, Allegheny county,Pennsylvania, have invented a new and useful Water-Cooled Reversin-Valve, of which the following is a full, c ear, and exact description,reference being had to the accom anying drawings, forming part of thisspeci cation, in which Figure 1 is an end elevation partly in section ofmy improved valve; Fig. 2 is a verti cal longitudinal section; and Fig;3 is a broken detail view of the valve proper.

Myinvention relates to the class of reversing valves forregenerative'furnaces; and is designed to mprove such valves byWater-cooling all the parts thereof, preventing any substantial leakageof gas, and giving them longer life.

In the drawings, 2 re resents a cylindrical double-walled casing avingfour doublewalled ports or channels '3, 4, 5 and 6 leading- 0st throughwhich the pipes 11 and 12 orming the trunnions for the valve 13 extend.The valve is of the butter-fly type, is hollow, and its outlet pipe12'is curved within the valveand extends nearly to its upper d e, so asto insure the valve being racti-' cal ly full of water at all times.have shown the inner wall of the chamber as provided with ribs 14against which the edges of the valve seat in its two ositions.

The water connections or maintaining the circulation may be'arranged inmany differ- In the form shown the amount of water supplied enters thevwall of the lower port 6 through the inlet 16. Water flows out throughthe casing and through the outlet pipe 17 in the top port, and thence isled through pipe 18 into the lower portion of the head 7. From the upperpart of the head 7 the water asses throu h outlet pipe 19 into pipe 11 wichfeeds t e water into the valve pro er. It then flows out throu h pipe12 and t ence through pipe 20 into the ower part of the opposite head 8.It then fiows from the upper part of this head through outlet 21. Thevalve may be swung b any suitable connections, such as the ban lever 22connected to one of the pipe trunnions.

The advantages of my. invention result from the simplicity and completewater cooling of thevalve in the casing. The casing maybe placed in manydifferent I either vertically or horizontally. T e Water connections maybe separate for different parts, and many otherchanges may bev ositionsmade without departing from my invention.

I claim 1- 1. A reversing valve having a double walled casing formedwith a plurality of port 7 openings, the walls of said 0 eni'ngsextending beyond the casing and aving annular water spaces therein whichcommunicate with the space between the double walls of the casing, andmeans for circulating water through the said s aces, some of thecirculating connections eing made directly to the spaces in the'portwalls; substantially as de-v scribed. I

2. A reversing valve, having a double wall casing with port-o eningstherethrou h, the ort openings a so having extended doub e walls whichare integral with-the adjacent cas ng wall, and the interior spaces oiwhich communicate with the interior spaces of the casing walls,substantially as described:

In testimony whereof, I have hereunto set my hand.

JoHN BARNES.
